Flow Bench

After all the porting, the head and manifold are analyzed and tweaked on the flow bench. It's mandatory that the flow rates from cylinder to cylinder are essentially the same (less than .5% deviation) at all valve lift points. The manifold is an extension of the intake ports, so it must be in place when flowing this side of the head. Exhaust pipes and header flange must be similarly used on the other side to obtain valid data.
